Title: Improvements in or relating to Water Desalination Processes and apparatus
Inventor: WALKER PETER THOMAS
IPC: B01D3/06
Filed: 1966-03-24
Abstract: 1,185,824. Evaporators, flash type; desalination of water. WEIR WESTGARTH Ltd. 28 March, 1967 [24 March, 1966], No. 13139/66. Heading BIB. Desalinated water is produced from brine (e.g. sea water) by passing the heated brine upwards through a tower 1, divided by horizontal plates 2 into stages connected by riser pipes 3, wherein flash vaporization of water into steam takes place in each of the successive stages, withdrawing the steam from the stages through separate conduits 5 leading to separate condenser sections, and withdrawing residual brine from the upper part of the tower through conduit 7. Vacuum is applied to the top of the tower by line 8 so that the pressure at the top is about 1 p.s.i.a. As shown, there are two condensers 9, 10 connected to vacuum line 13. Each condenser is divided into sections by partitions 15 which do not make completely steam-proof with thewalls and cooling tubes 12 of the condensers, so that the degree of vacuum decreases from the right-hand or cool end of condenser 10 to the left-hand or hot end of condenser 9. The condensate formed in condenser 9 is collected in troughs 16 and conveyed by conduit 17 to the troughs 18 in condenser 10, from which the required fresh water product is withdrawn by conduit 19. Brine is introduced into the tubes of condenser 10, and the slightly warmed brine flowing out of the outlet header 11 is divided into two parts, one of which is discharged to waste through conduit 22. The other part is mixed with some of the residual brine from the top of the flash tower, and the mixture is passed through conduit 25 into the tubes of condenser 9. The brine leaving the other end of the tubes of condenser 9 is passed through steam-heater 27 and then introduced into the base of tower 1 through conduit 6.

Title: Improvements relating to speed indicators
IPC: G01P3/02
Filed: 1924-05-30
Abstract: 217,214. Fabriques des Montres Zenith, (Successors to Fabriques des Montres Zenith G. Favre-Jacot et Cie). June 9, 1923, [Convention date]. Differential speed indicators of the type in which the speed indication is effected by two members, one of which is driven at a speed corresponding to that to be measured, and the other is arranged to move periodically at a speed following a predetermined law. The element 3 is driven by a pinion 3<a> at a speed equal or proportional to that to be measured and drives through a coiled spring 5 a balance-wheel 4. Once every revolution the balance-wheel is arrested and its spring coiled up by the engagement of an arm 32 upon it with a pin 18 carried by a spring-pressed lever 17 pivoted to the casing at 16. After an interval it is released when a pin 19 on the disc 3 engages the arm 17. This position is shown in Fig. 3, the relative position of the parts when stationary being shown in Fig. 2. Upon release the wheel 4 accelerates under the action of the spring 5 and moves forward until a pin 23 upon it catches up to and engages an arm 22 of a lever 10 pivoted at 9 to the rotary disc 3. Means are provided for positioning the indicating pointer 40 when this engagement occurs. Upon the pointer spindle, movement of which is restrained by a spring 41, is fixed a toothed wheel 6<a> meshing with a loosely mounted toothed disc 6. A spring-pressed pawl 14 mounted between the 6 and a bridge-piece 12 carries a bar 15 one end of which engages the teeth of a fixed ratchet 7, the other end being adapted to be engaged by a second arm 24 of the lever 10. The lever 10 has also a nose-piece 25 adapted to engage a projection 26 on the bridge-piece 12. When the speed to be measured is increasing the nose 25 engages the projection 26 for a period before the pin 23 engages the arm 22 and displaces the nosepiece. In this way a movement is transmitted to the disc 6 through the bridge 12, the pawl bar 15 meanwhile riding over the ratchet 7. When the speed is decreasing, the pin 23 catches up to the arm 22 before the parts 25, 26 have engaged, and the arm 24 is caused to lift the bar 15 off the teeth of the ratchet 7 so as to permit a backward movement of the pointer 40 under the influence of the spring 41. A clip 31 mounted on the disc 3 is engaged by the blade 32 and provides a deadening stop for the balance wheel 4 at the end of its relative movement. In order to prevent the instrument from being damaged should the speed exceed the maximum for which it is constructed, the pivot 9 carrying the lever 10 is adapted to be rocked by the engagement of a pin 27 with a fixed cam 28 and disengage the parts 25, 26 if this has not already been effected by the pin 23. Modifying scale of readings.-The form of the meshing toothed wheels 6, 6a is not circular, but is selected so that the movement of the pointer 40 is proportional to the speed of the wheel 3. Registering distance upon counters.-An odometer is actuated by a lever 45 which has a finger engaging a circular cam groove 34 in the wheel 3.

Title: Improvements in or relating to process of preparing glutamic acid
Inventor: HOGLAN FOREST A
Filed: 1953-05-14
Abstract: A substantially ash-free glutamic acid and glutamic acid mother liquor are obtained by a process comprising hydrolysing a proteinaceous composition with sulphuric acid, treating the hydrolysate with a sufficient amount of alkaline earth metal oxide, hydroxide or carbonate to adjust the pH of the hydrolysate to between 8 and 12, separating insoluble matter from the mixture, heating the remaining solution until the vapour is substantially free from ammonia, adding to the remaining alkaline solution an acid or acid anhydride which forms a water-insoluble alkaline earth metal salt in an amount sufficient to adjust the pH to between 4 and 7, crystallizing and separating tyrosine and leucine from the adjusted solution, treating the tyrosineleucine mother liquor with an additional amount of the acid or anhydride to adjust the pH to between 2.5 and 3.5 thereby co-precipitating a mixture of alkaline earth metal salts and glutamic acid, separating the coprecipitate and treating it with an aqueous solution to dissolve the glutamic acid, and separating the insoluble alkaline earth metal salts followed by crystallizing glutamic acid from the solution.  The process is applicable to the treatment of proteinaceous material such as wheat gluten, corn gluten, casein, peanut meal, soybean meal, cottonseed meal, albumin, linseed meal, flaxseed meal, and bloodmeal.  Suitable acid materials are, for example, sulphur dioxide, sulphuric acid and carbon dioxide.  In the examples wheat gluten and corn gluten are treated according to the process of the invention to give glutamic acid with some tyrosine and leucine and less amounts of methionine, phenylalanine and valine.  U.S.A. Specification 2,598,341 is referred to.

Title: An improved apparatus for indicating the approach of trains
IPC: B61L1/04
Filed: 1924-06-04
Abstract: 238,969. Taylor, G. June 4,1924. Approach of trains, alarms apparatus for warning of.-A portable apparatus for giving warning of approach of trains comprises a treadle mechanism, Fig. 1, which is secured to one of the rails by a screw clamp and includes an electric switch in a barrel l which is connected by fexible leads to a bell and lamp signalling device. The treadle lever b is counterweighted and carries a convex head c for depression by the train wheels and a projection d which coacts with a bell crank lever e to lock the lever in its depressed position until released by magnetization of the magnet f, the armature of which strikes a blow on the lever e to displace it from its locking position. Fig. 4 shows the electric circuits. Depression of the treadle opens the contacts in the barrel l and de-energizes relay p; the indicator q is thereby energized and closes its contacts y to complete the circuit to the lamp sand bell r. These continue in operation until the switch t is closed to energize the releasing magnet f. The relay p is thus re-energized and the indicator q may be replaced by hand since its coils are then de-energized.
